There could be dozens of variables that affect how sore you get, but overall some degree of soreness is to be expected for a lot of people (my injections always turn out to be very sore, personally). What you should watch for are odd discolorations of the skin, cysts forming, or anything that might look like an infection.
P.S. I hope you're either single, or in prison. Because you won't be having much use of your testicles or penis with that cycle.
